There are some general tips for using essential oils that apply regardless of the type. You want a high-quality therapeutic-grade oil. They are amazing for Diffusers - always use 100% pure! Never apply most oils directly to your skin, as their high concentration can cause a reaction or irritation. Instead, essential oils should be diluted with water or a carrier oil like jojoba, grapeseed or almond. And with a few exceptions, do not ingest essential oils. And always talk to your doctor about health concerns, especially if they represent sudden changes in your well-being.
